The IOPS (Intra-Operative Positioning System) is intended for the evaluation of vascular anatomy as captured using 3D modeling from previously acquired scan data. It is intended for real-time tip positioning and navigation using sensor-equipped, compatible catheters and guidewires used in endovascular interventions in the peripheral, aortic and aortic side branch vasculature. The system is indicated for use as an adjunct to fluoroscopy. The IOPS does not make a diagnosis.
